—BioNano Genomics, a nanotechnology startup that moved to San Diego from the Philadelphia area about two years ago, unveiled an automated benchtop instrument called the Irys System that takes a new approach to gene sequencing. The company says its technology images extremely long strands of a single DNA molecule, enabling scientists to visualize the genome architecture in its native state. Instead of fragmenting and amplifying DNA, BioNano Genomics says the Irys System uses proprietary technology to uncoil and confine long DNA molecules in nanochannel arrays.
